Description Kurt Seifried 2011-12-23 02:40:57 UTC 
https://blog.torproject.org/blog/tor-02234-released-security-patches

Tor before 0.2.2.34, when configured as a bridge, sets up circuits
through a process different from the process used by a client, which
makes it easier for remote attackers to enumerate bridges by observing
circuit building.
